Under the leadership of its founder, blockchain enthusiast Patrick Byrne, Overstock.com owns and operates tZERO and Medici Ventures in addition to being a tech-focused online retailer. Overstock.com is a publicly traded company whose largest shareholder is Byrne with a 20.2% holding.[1]

Overstock.com was one of the first retailers to accept bitcoin as payment by customers for goods.[2]

With its focus on blockchain technology and bitcoin, Overstock.com shares suffered as the prices for cryptocurrencies receded throughout 2018 losing 21% of their value by August, well before the markets-wide fourth quarter share price rout.[3]

In September 2018, Byrne told Forbes in an interview that Overstock.com would begin selling bitcoin on its website early the next year using the new Bitsy wallet. Bitsy, which is designed for easy use by Overstock.com's non tech-savvy customer base, is owned by Medici Ventures.[4]

In November 2018 Byrne told the Wall Street Journal that he has been planning to sell Overstock's retail business, leaving the company with Medici Ventures and tZERO.[5]

On January 3, 2019, the company announced to its investors that it would pay some of its ongoing business taxes in Ohio through that state's first in the nation crypto-payments service, OhioCrypto.com.[6]
